Soundproofing

I have an unfinished basement space, roughly 1000 sqft that I would like to convert to a TV and 2-channel listening room. The ceiling is open floor joists to to the first floor, any recommendations on soundproofing materials that I could use to rough finish between the joists. Floor/ceiling joists are 2x10's.

Thanks,
David

Most materials sold by places like ASC and GIK (my fave) won't help you.


You need mass. The best Ideas I've read about are to use 2 layers of drywall with resilient channel in between. I encourage you to google for more specific solutions.


Here is one example, maybe it will help you on your journey

PS -

ASC and GIK are great for treating how the INSIDE of your listening room sounds, and they may also have sound proofing materials.
What I meant to say is that the two types of products and practices are different.

I have done the two drywall layers with a "a channel" between them. It works very well. However, bass waves are so long, it's pretty hard to keep them from penetrating and leaking into other rooms.
